Lichenicolous ascomycetes on Siphula-like lichens, with a key to the species
Sixteen species of lichenicolous fungi are documented from Siphula-like lichens. Two new genera based on new species are introduced. Amylogalla Suija, Motiej. & Kantvilas, characterized by I+ blue, K/I+ violet vegetative hyphae and ascomatal wall, immersed, cleistohymenial, yellowish to orange a...
